How Long Can You Stay in the US on a B-1 Visa?

You can stay in the United States on a B-1 visa for up to six months per trip in most cases, and no more than one year total including any extension. The exact date you must leave is set by the Customs and Border Protection (CBP) officer when you arrive and is recorded on your electronic I-94, not on the visa sticker in your passport.¹

Where Your Departure Date Actually Comes From

At the port of entry, a CBP officer looks at your passport, your business purpose, and your supporting documents, then grants an admission period suited to your trip. The maximum is one year; six months is typical.¹ Someone flying in for a three-day conference may be admitted only for as long as the event requires. The officer’s decision is final for that entry.

That decision shows up as the “Admit Until Date” on your electronic I-94, which is your legal proof of admission.² That date, and only that date, controls when you must depart.³ Pull up your I-94 online through the CBP website as soon as you clear immigration. If the officer gave you less time than you assumed, you want to know immediately, not weeks later.

Why the Visa Sticker Date Doesn’t Tell You When to Leave

This confuses almost everyone the first time. The expiration date printed on your visa sticker is the last day you can show up at a U.S. port of entry and request admission.⁴ A ten-year, multiple-entry B-1 gives you a decade of chances to knock on the door. It says nothing about how long you can stay once you’re through it.

Each admission generates a fresh I-94 with its own deadline. You could have seven years left on your visa sticker, but if your I-94 says March 15, you must be out by March 15.

Extending Your Stay Beyond the Original I-94 Date

If your business runs longer than the time you were given, you can ask USCIS for more time by filing Form I-539, Application to Extend/Change Nonimmigrant Status.⁵ The total stay, counting the extension, still cannot exceed one year from your original entry date.¹

You need to show a real business reason for the extra time, such as a negotiation that has run long or an event that was rescheduled. You also need to show you can support yourself without working. Gather bank statements, an updated itinerary, and a letter from your U.S. business contact explaining why the additional time is necessary. Every name and date on the form should match your passport and I-94 exactly; small mismatches cause delays.

Timing the Filing

USCIS recommends filing at least 45 days before your I-94 expires, and no earlier than six months before.⁶ Filing late is the most costly mistake in this process. If USCIS receives your application after your I-94 has already expired, the agency will generally deny it unless you can prove extraordinary circumstances beyond your control caused the delay.⁷ Fees are non-refundable even if the request is denied.

What Happens While You Wait for a Decision

When USCIS accepts a timely-filed extension, you receive an I-797C Notice of Action confirming receipt.⁸ While the application is pending, you’re generally in a period of authorized stay even after your original I-94 date passes, and you’re not accruing unlawful presence.

Two limits matter. You can’t work while waiting, and you can’t leave the country. Departing the United States with a pending I-539 abandons the application; if you go, you’ll need a fresh admission when you come back.

If USCIS denies the extension, everything shifts at once. Your visa is voided by operation of law, you’re expected to leave promptly, and unlawful presence begins accruing no later than the denial date.

What Overstaying Costs You

Staying past your I-94 date sets off consequences that can follow you for years. First, your visa is automatically voided under federal law; any future entry requires a brand-new visa from a consular post in your home country.⁹

Then there are the re-entry bars under federal immigration law, which turn on how long you overstayed:¹⁰

More than 180 days but less than one year of unlawful presence, followed by voluntary departure before removal proceedings: a three-year bar on re-entry.
One year or more of unlawful presence: a ten-year bar, whether you leave voluntarily or not.

These bars apply across the board, not just to future B-1 requests. A business-visit overstay can sink a later work visa, student visa, or green card application. Check your I-94 the day you arrive, set a calendar reminder well ahead of that date, and either book your flight home or file the extension before the deadline hits.

Frequent Trips and the Re-Entry Question

Nothing in the rules caps how many times per year you can visit on a B-1. But CBP watches travel patterns closely. If most of your calendar shows time inside the United States with brief hops out, the officer may decide you’re effectively living here on a visitor visa and refuse admission.¹¹

Two practical points on re-entry. A short trip to Canada or Mexico of 30 days or less during an existing stay is treated as a continuation of your original visit, so your original I-94 date still governs when you must leave.¹¹ Travel to anywhere else and return counts as a new admission, with a new inspection and a new I-94. The second inspection can be more thorough if the officer sees a pattern of long U.S. stays. Carrying documentation of strong ties at home (property, ongoing employment, family) helps.

One Boundary Worth Knowing: The B-1 Is Not a Work Visa

The duration rules above assume you’re doing what a B-1 permits: consulting with business contacts, attending conferences, negotiating contracts, participating in short-term training, or settling an estate.¹ You can’t perform work for a U.S. employer or take pay from a U.S. source, even if your foreign employer is still paying you. A finding of unauthorized work ends your authorized stay regardless of what your I-94 says, and it triggers the same voided-visa and bar consequences described above.

Visa Bond Rules for Some Nationalities

Starting in 2025 and expanding through 2026, the U.S. Department of State requires nationals of dozens of countries to post a refundable visa bond of $5,000, $10,000, or $15,000 as a condition of receiving a B-1/B-2 visa, with the amount set at the visa interview.¹² Listed countries include Nigeria, Bangladesh, Ethiopia, Cuba, Venezuela, Nepal, and others across Africa, Asia, the Caribbean, and Central America. The bond is refunded if you comply with the terms of your stay, including leaving on time; if the Department of Homeland Security finds you breached your status, the full amount is forfeited and future visa eligibility suffers. Check the State Department’s published list before your interview so you know whether the bond applies to you.
